What happened
Micron tripled fiscal second-quarter sales year-over-year to $23.9 billion, driven by surging demand for high-bandwidth memory (HBM) chips. Gross profit margins swelled to 74.4% from 36.8% a year prior, as a global shortage of memory chips, fuelled by AI data centre construction, increased prices. Micron is shifting production focus to HBM, moving away from less profitable DRAM and NAND. The company projects capital expenditures exceeding $25 billion this year, with an additional $10 billion increase for the next fiscal year.
Why it matters
The escalating cost of high-bandwidth memory will directly impact procurement teams and platform engineers building AI infrastructure. Micron's increased capital expenditure, projected to exceed $25 billion this year with a further $10 billion increase next fiscal year, signals a sustained supply constraint and higher pricing for essential HBM components. This shift in production focus from DRAM and NAND to HBM locks in higher costs for traditional computing hardware, affecting consumer electronics and enterprise IT budgets.
